Assuming the given scenario is a right angle triangle; (it helps to draw a diagram of the person and what they are seeing to better understand this question). 

tanФ=opp/adj 
tan(24)=(height of building)/280
280×tan(24)=height of building 
124.66 m = height of building. 

Hope I helped :)

Find the radius of the cylinder when volume is 304 cm^3 and height is 10 cm
aleksandr82 [10.1K]

Answer:

<h2>3.11 cm</h2>

solution,

Volume of cylinder=304 cm^3

height=10 cm

Radius=?

Now,

volume = \pi  {r}^{2} h \\ or \: 304 = 3.14 \times  {r}^{2}  \times 10 \\ or \: 304 = 31.4 \times  {r}^{2}  \\ or \:  {r}^{2}  =  \frac{304}{31.4}  \\ or \:  {r}^{2}  = 9.68 \\ or \: r =   \sqrt{9.68}  \\ or \: r =  \sqrt{ {(3.11)}^{2} }  \\ r = 3.11 \: cm

Hope this helps..

Good luck on your assignment..

2*10⁴-7³ please help​
melisa1 [442]

Answer:

19657

Step-by-step explanation:

By PEMDAS, we know we have to calculate the exponents first, then multiply the 2, and then subtract the 7³

2*10⁴ = 20000

20000 - 7³ = 19657

This is the third time I've seen this question. Are you posting this question again and again?

What value of t is the solution of the above equation?
mel-nik [20]

Answer:

15/4, or 3 3/4 is your answer.

Step-by-step explanation:

Isolate the variable, t. Note the equal sign, what you do to one side, you do to the other. Multiply 3/2 to both sides.

(3/2)(2/3)t = (5/2)(3/2)

t = (5/2)(3/2)

t = 15/4

15/4, or 3 3/4 is your answer.
